The irony is that Ghrelin the hunger hormone increases intelligence. Its nature's way of helping mammals become innovative in obtaining food. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2805706/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2805706/ "Ghrelin also promotes rapid reorganization of synaptic terminals in the hypothalamus28, and in the hippocampus it promotes synapse formation in dendritic spines and LTP, which are paralleled by enhanced spatial learning and memory formation29." I am amazed at how much the financial system imitates what life would be like living in the wild 1000's of years ago.

While that may be true, I would caution about thinking that hunger promotes intelligence in the long term in any way. I'm not an expert but I would confidently bet that the effects of malnutrition on cognitive ability FAR outweigh this hormonal effect.

  Note that they're talking about a hormone that gives the feeling of hunger, rather than hunger as a result of malnutrition

    Benzoic Acid and its derivatives (Sodium/Potassium/Calcium) Benzoate affect Leptin, another hunger/satiety hormone.

Considering how obese the West is, is it any wonder why the West is losing its edge, especially the US? Now malnutrition is different to being hungry, you can be obese and suffering from malnutrition. A purified diet is malnutrition. Its why if you are in the US army and you get slammed in the can for punishment, you only get bottled water and a multi vitamin pill as your nutrition for the time you spend in there. Thats all you need to know to get your fighting spirit back!

      Why do you think this is correlation?

        Obesity trending upwards since X West in decline since X+c Voilà, obesity = decline.

        Yes but there is science that backs it up and I'm not paid to convince you otherwise.

Except it doesn't because what actually happens when people are in poverty is they can't escape for a whole litany of reasons that have nothing to do with intelligence: the stress of being borderline able to pay bills and having to work long hours mean they have no capacity to think about how to improve things, or even basics like healthy eating; they can't afford to buy ingredients in bulk so they're forced to buy much less efficiently and so spend more; the health effects of poverty, both direct and indirect put additional time and cost pressure on them; etc etc. Don't get me wrong, the fact that ghrelin may have an impact on intelligence is fascinating, I just don't think it has anything to say about poverty.

  True there are a whole litany of reasons. I dont think anyone works harder than the self employed. I've done 80hrs straight, and I've not met anyone who has been at work for longer than that. Not parents, not nurses, coppers or soldiers, or cleaners. I've gone with out food for 18days, just water. And I'd do it again if I needed to. I've slept on the streets, had people want to beat me up but for their sake, I'm glad they didnt try! Stupidity really annoys me, but as noone ever gets their exam paper back and checks their answers against the text books, how can anyone claim to be qualified? An exam result is little more than a medal or some other form of social division with an element of social conformity.

Huh, would this be noticeable from e.g. intermittent fasting?

  So the problem with fasting is it depletes things like glutathione from the liver. Fast too much and the body will catabolise itself, ie loss of muscle mass and so on, plus things like ketosis acidosis can be a risk for some. The hygienists (1950's US based org headed by a bloke called Shelton) were into fasting and it was what Christians Lent was originally about. Now water is also a factor with fasting so if you take Islam's no food or drink during daylight hours, that type of fasting caused an increase in blood sugar levels due to the lack of fluids. When you have no food or drink parts of the immune system increase rapidly and will attack the body so you get into autoimmune disease territory. The world record is actually 382 days done in 1971 at the University of Dundee. Just water and electrolytes, but the bloke started from an obese state in the first place. He might still be alive today. There are risks with many things, not only eating (diabetes/protein rich depression) but different types of fasting. Even the paleo diet which is like a ketogenic dieting has its risks. So thats protein rich, but some chemicals like tryptophan will not be absorbed in the presence of other proteins, they compete in the gut. Copper & Zinc iirc also compete. Then there is the form so we have a gut enzyme which limits our ability to absorb ferric iron ie fe3 or iron oxide (the brown rust you get when you cook meet), but its possible to absorb lots of ferrous iron (fe2), but then too much iron can cause its own problems like internal bleeding. Ultimately it depends on what your goals are for intermittent fasting in the first place.
